SQL/DB Error after install beta 5

[mtmdali]

I reinstall beta 5 and mysql 5 (windows)
(The Server Type Dialog
choose 3rd option

Dedicated MySQL Server Machine: Choose this option for a server machine that is intended to run only the MySQL server. It is assumed that no other applications are running. The MySQL server is configured to use all available system resources.

2.3.5.6. The Database Usage Dialog

choose 3rd option also

Non-Transactional Database Only: This option disables the InnoDB storage engine completely and dedicates all server resources to the MyISAM storage engine. This option is recommended for users who do not use InnoDB.
)

After install db to create all 9 tables, there is still problem with submit a story .
I guess if use InnoDB the table links can not be created automatically.

Warnings:

SQL/DB Error -- [Field 'link_title' doesn't have a default value]

and

incorrect key

after submit by press button "continue"
